Solar Panels Cost

One thing that puts many people off from seriously considering solar panels for energy generation is the perception of cost.


Solar panel prices may appear expensive, but when considered over the length of time they last, how much income you can make from them and how much money you can save through your electricity bill, the price begins to look more reasonable. But there are many other factors that need to be taken into amount when weighing up the value of solar panel prices.


The amount of power needed will affect solar panel prices

How much power you use in your home determines how many solar panels you will need to link together into an array. Solar panel (also known as PV systems or photovoltaics) are measured according to their peak power rating – that is the maximum amount of power they can convert when they are running at their peak of performance. This is known as kWp or kilowatt peak. Generally, a 1m2 panel will produce 1kWp.


To work out what size panel you need, you first need to know how much electricity you use per year in kW. Your electricity bills will tell you how many units of electricity you use quarterly, and usually also works out the conversion to kW, but you’ll need to add them up to find out your annual usage. Once you have this, add another 10-20% onto this figure to take account of any unexpected higher usage by an electrical item, for example, if you replace something and the new item draws more power, or you buy an additional device for your home.


Being connected to grid means there’s no problem if your panels don’t generate enough power now and then, but if you want to sell your surplus to the electricity companies you need to be able to generate more than you are using.

Type of panel will affect solar panel prices

Solar panel prices vary according to whether they are monocrystalline, polycrystalline and amorphous.


Monocrystalline are the most expensive, but also the most efficient as they can convert around 15-17% of the sunlight that hits them. Some panels have been known to be able to convert as high as 21.5%. Polycrystalline are a little cheaper, but this is reflected in the fact that they have an efficiency rating of around 12%. Finally, there is amorphous solar panels, but these only convert 6% of the sunlight that hits them yet can be more expensive than polycrystalline as they are not as popular and not manufactured in great quantities.

The more efficient the panels, the smaller the size of the array needed, but efficiency can vary according to manufacturer. The University of Oxford’s Environmental Change Institute found that the amount of kW produced by a standard 1kWp array could vary by as much as twice the amount when comparing the highest yielding to the lowest yielding systems.

As a very rough rule of thumb, in the UK a 1kW system can produce up to 850kW a year.


The amount of power needed will affect solar panel prices

Intensity of light will affect solar panel prices. Not everyone can have solar panels due to their requirements for a minimum amount of light intensity.


The amount of light that falls on a panel depends on your geographical location, angle the panels are installed at and the time of year. In the UK the least amount of sunlight that falls on a panel during the year will be mid-winter at approximately 60 degrees from the horizontal. To generate 1kW of electricity you would need to have a 1kW panel. Compare that to the South of France, where you might get 3 or 4 hours of sunlight per day and only need a 0.5 kW panel!


However, solar panels are sensitive to shading. There are two types of shading; soft and hard. Soft shading is classed as something like a tree branch, chimney or roof vent which creates a diffuse shadow. Hard shading on the other hand is something that stops light from reaching the solar panel, such as trees, buildings or bird droppings.



Installation costs will affect solar panel prices

These can vary depending on the size of the installation, the quality of training the installers have and the amount of work and materials needed to mount it onto a roof.


For obvious reasons the more power you need, the more solar panels you need and these can be the most expensive part of the installation. Usually the first kW is the most expensive with costs dropping thereafter for every additional kW due to economies of scale.


As the output of a solar panel is Direct Current (DC) and UK properties are run on Alternating Current, an inverter and voltage regulator will be needed to match up with the properties electricity supply and the National Grid. Besides the panels, this is the next most expensive item in an installation. Every panel requires mounting hardware to attach it to a roof, while the labour costs of installing the panels plus 5% VAT on the cost of the whole job must also be factored in.


Finally, care must be taken to ensure you use the right company to install your panels as this can affect solar panel prices. If you want to obtain Feed-In Tariff payments, the company you use must be registered with the Microgeneration Certification Scheme (MCS). This Scheme ensures the installers have achieved a high standard of workmanship when fitting solar panels. The amount of money a company spends to achieve this standard through extensive training is usually part of the labour costs of the job. It pays not to skimp on this aspect of the job, as poorly installed panels are likely to generate less power and may take many more years than quoted to pay back.


There was a time when solar panels prices were enormous, but advances in technology, manufacturing efficiencies, government grants and installer offers has brought the price down to a point where – given the right light conditions – almost everyone in the UK could have solar panels generating electricity for them.
